名爵汽车底盘连接片连续模设计 摘要 随着全球的互通发展我国经济的蒸蒸日上，各行各业的发展都离不开模具，尤其在汽车，机械等领域方面我国取得了巨大进步，模具制造业在我国的发展已经从原来的低谷逐渐上升。本次课题是有关汽车底盘连接片连续模设计及制造的研究，概括起来其内容主要有对模具行业发展的分析、连续模在模具制造中的地位以及作用、UG技术的简介、冲压模具设计的基本方法、模具工艺分析以及模具零件和整体设计。这次设计的汽车底盘连接片连续模，该类模具是多任务冲模，有良好的工作效率，此零件在冲压环节精度高。本次设计的连续模主要的工序是冲孔和落料两部分，其中就需要对模具的压力机的选取，压力中心的计算，冲裁力的计算，凸凹模尺寸以及模具模架尺寸的计算和选用。其次运用UG软件对模具进行结构分析，画出毛坯进行加工。 关键词：连续模；尺寸计算；零部件选用；UG制图； ABSTRACT With the developme
